Introduction to external insulation technology
In the building, the heat loss of the outer wall envelope structure is large, and the wall body is the main component of the outer guard structure. According to the value engineering principle, the development of the outer wall insulation technology has become an important part of building energy conservation, which not only saves A lot of energy can also provide residents with a comfortable environment and bring many benefits.
The urgency of building energy conservation
With the annual use of 1 billion square meters of civil buildings in China, the proportion of building energy consumption to the total energy consumption of the whole society has increased from 10% in 1978 to 27.5%, making the building a major energy consumer in China. Continued consumption of a large amount of energy poses a serious threat to industrial use. To this end, the country began to enforce the 50% standard for building energy efficiency in 1997, and vigorously developing energy-efficient housing has become a top priority.
